Im following this here:
http://www.techzek.com/how-to-root-samsung-galaxy-s-blaze-4g-sgh-t769-smartphone/
But the power, vol up and down get it to show the yellow "warning" thing that im supposed to see, but it goes away after like half a second so I cant get into it. What else can I do?
how to get to download mode.
As you press the volume +/- and power button , simultaneously plug the micro usb cable into your phone (this cable should already be attached to your pc). This should do the trick.
Happy rooting.
The instructions in the first post are wrong, and should be updated. You have to have the cable plugged in. In the video for example, he has the phone plugged in the entire time. You're not required to have three hands in order to get it done.
I've had no luck with any of the variations on this method either.
Turn your phone off, hold both volume buttons and with your usb plugged into the computer take the other end and plug it into your phone while continuously holding the volume buttons. It will boot into the caution screen and than you press up to get into download mode.

If none of the above still don't work try this
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down
7. While still holding the volumes insert battery
8. Should now be in download mode

Thank you both for the replies. I've tried both methods several times without success. I'm tired now so I'll quit for the night. I'll try again tomorrow a few more times. If I can't get it to work I'll take it as a sign that I'm not meant to root this phone. I must have tried 30 times today; it gets old.
Update:
I've tried this ten or fifteen more times. I'm finding that the yellow warning message, whatever it is, doesn't appear at all, ever, unless the USB cable is not connected when I put the battery in. If the USB is connected, I get the gray battery icon every time, no matter what else I do.
If I do connect the USB, with the battery out, I immediately feel the device vibrating every second or so, as if reboooting.
I tried removing the SIM and SD cards again. This had no effect.
It's very strange. In that video the entire process looks about as easy as doing a simple battery pull. It's just not working for me. Is it possible that Samsung made some of these phones "root-proof"?
Worst case scenario you will have to buy a Samsung jig.

I had to do it a few times myself.... It did not catch for me the first 3-4 times...
Then it worked. Make sure you are holding down all 3 buttons down tight.

I think I've tried it at least 50 times now, with variations, and it's just not happening. I freely admit my ineptness, but holding down buttons is something even I can manage.
By "three buttons", I take it you mean two. I don't have separate volume up/down buttons on my Blaze; just a single rocker button. That's what you mean, right?
I did get as far as the warning screen, but from that screen there is no option for pressing up to go into download mode, so it seems that my warning screen is different from others'.
I guess the next thing is to research "Samsung jig" and figure out whether this is something I can possibly do.
I went through the same thing, I too thought I had to purchase a jig but the method I posted thanks to another member saved me, try again with a modification to step 6
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down + power buttons
7. While still holding the volumes insert battery

Thank you. I just tried it a couple of times, without success. I have to go out now, but I'll give it another few tries later.
If I have to get a jig, should the Samsung Galaxy S be compatible? I'd think so, but I don't know for sure.
This is a slight variation of what everyone is suggesting...I was also getting vibrations when trying other methods.
Turn off phone
Unplug battery
hold volume rocker, make sure you're holding down both up and down
Insert battery
Hold power button until the warning comes up...only takes a few seconds
I said three buttons, because it seemed (at least to me) that you need to hold sides of the volume button down at the same time. It does not seem to be just a up/down button.

Thanks for this suggestion, but it also didn't work.
This method, like some of the others, takes me into what I think is Recovery Mode. I'm not sure, because I don't really know what I'm doing. The message that flashes on the screen isn't really a warning. Doing it this way, i.e., releasing the power button but not the volume button after the phone starts, takes me to a screen that says,
Android system recovery <3e>
at the top. Then there are some options: reboot system now, apply update from sdcard, wipe data/factory reset, wipe cache partititon. I can use the volume button to select an option, and the "OK Key", whatever that is, to select.
Near the bottom of the screen, in yellow, is the text that I couldn't read before:
-- Verifying internal MMC block...
checksum confirmation -> check(0)
Not need checksum confirmation
already executed!!...
# MANUAL MODE #
And that's it. In the background of this screen, grayed out, there's a white triangle with a yellow exclamation mark in it and a little green android.
Is there a way to get from this screen to Download Mode?
adb reboot download
should get ya

I guess it might if I could get ADB to work. So far, no luck; but that's a whole different problem. There are pages upon pages of posts here from people having difficulties getting ADB to work, so it'll take days or weeks to sift through all that and figure out what I'm doing wrong.
I thought the actual rooting process would be fairly simple, and it would only get complicated when trying to install custom ROMS and that sort of thing, which I'm not trying to do. It appears that I was wrong. I think I just don't have the knowledge to do this.

Make sure you have Kies Air turned on when you try to connect. You can use USB or wireless mode then. I tried and without Kies, it would not connect.

So I should have debugging mode and Kies Air turned on, and then ADB should be able to find the Blaze? I'll try it tomorrow.
Thank you.
Hi,
My tf300t got its screen cracked so touch screen is non functional.
I'm trying to turn it off so I can open the case, but it always reboots no matter what I try!
Tried long pressing the power button for 30 seconds but it always reboot after 8 seconds.
Any suggestions? I don't want to open it up while it's on .
Can I shut it down from fastboot mode?

I remember there was a manual Power off option in TWRP (idk if it is still there). Have you tried that?

I have the stock bootloader - it says
Code:
"Adroid cardhu-user bootloader (1.00 e) released by "WW_epad_10.4.2.9-20120809" A03
I'm inclined against flashing a bootloader (only as last resort).
I am able to get into fastboot and issue fastboot commands. will that help?
"fastboot reboot" only reboots..
by the way, the device is still locked (getvar returns "unlocked: no")..

How did you turn it off if the touchscreen wasn't working? By pressing the power button would cause it to reboot endlessly. If you don't have a dock or adapter to power off properly, one thing I did before was to click the reset button (through the hole below the SD card slot) and press the power button simultaneously, then keep holding the power button for 10 seconds after releasing the reset. It did turn off the tab completely. Failing that, just pop off the back cover and turn off the service switch. The cover is not connected to anything electronic so it's ok. That'd cut off the current to the tab. It can be done, just be careful.

I didn't turn it off, that's the problem.. I got it yesterday from a guy after his screen cracked.
he gave it to me turned on and I want to replace the screen, so the only thing I can use are the hard buttons.
I only have the power adapter + usb cable.
are you sure about that reset button thing?
EDIT: found info about the "service switch": http://forum.xda-developers.com/showpost.php?p=46159071&postcount=5
EDIT2: did it! thanks graphdarnell!!
now moving to step 2 - ordering a replacement digitizer..
Hi folks. I've got a problem that I don't see anything quite matching in here. I have a Straight Talk/Verizon GS7. Last night I installed an app do to USB tethering on it. It worked great for the testing. After I disconnected and it sat idle for a while, I heard a notification sound and the blue light started flashing. I push the home key and the "back" and "window" key lit up, but the screen is black.
So here's what I've tried so far.
I tried to hold the power button to turn the phone off. Nothing.
I can soft reset by holding volume down and power. I get the splash screens for GS7, Samsung and TracFone. Then BSOD.
I can't get safe mode. I can't get recovery mode.
I can get to download mode. "Volume down, home, power"
The phone has developer tools turned on and USB debugging is enabled. Is there a way to do anything helpful from download mode? I'm not too concerned about losing data, so flashing a new ROM is fine by me.

hi
Seem like flashing a new firmware may be the reasonable option...
Try flashing first with home_csc if you know what your CSC is at the moment..that way you may avoid losing your data
if that option is off the table...then use CSC and flash/ format your phone...
for your reference check here

Pay attention to step 6 if you use CSC
Thank you for the response. While I was downloading the ROM I came across "Vysor" and was able to use it to control the phone. Using it I was able to get the phone to power off and get into recovery mode. I wiped the cache partition and uninstalled the Tether app and all is good now. Now I just have to decide whether or not to cancel the RMA that Straight Talk is sending me...

Hello everyone
Please help me
I have a Sony Xperia Z3 Dual D6633 with Android 4.4.4
Firmware is D6633_23.0.F.1.74_CE
I tried to install TWRP on my phone using this tutorial
https://forum.xda-developers.com/z3/development/root-stock-kernel-twrp-v01-test-28-09-t2889794?__utma=248941774.950623471.1412017766.1412017766.1412017766.1&__utmb=248941774.1.10.1412017766&__utmc=248941774&__utmx=-&__utmz=248941774.1412017766.1.1.utmcsr=l.facebook.com%7Cutmccn=(referral)%7Cutmcmd=referral%7Cutmcct=/lsr.php&__utmv=-&__utmk=228295838
Since the links in the thread are down it was hard for me to get the bootZ3dualmonxtest01.img file
But after an hour of googleing finally I got it from another Android forum https://mdforum.ru/showthread.php?t=16534
Then, as mentioned in the tutorial I went into bootloader / fastboot mode and entered following command
fastboot flash boot bootZ3dualmonxtest01.img
But it didn't work. Now my phone is bricked. It's powered off and I can't turn it on again
It doesn't respond to anything
Pressing Powerbutton - Nothing
Pressing Power + Volume Up/Down - Nothing
Hold Volume down and connect to PC - Nothing
Connect to 230V Adapter for charging - Nothing
ADB doesn't recognize the phone
Flashtool responds "Device disconnected"
So I can't flash back stock ROM
Please help me out. What went wrong? How can I fix it? Is it repairable or is my phone hard bricked?
Thank you for your answers
Edit:
After several hours of googleing and trying I found a solution that worked for me

To force the device to restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") until the device has emitted three vibrations, and then release the OFF button. The device turns off automatically.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
If a forced restart procedure as described above doesn't succeed in turning on your device, you should try another kind of forced restart - the 2-minute restart procedure.
To force a 2-minute restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") for 120 seconds (ignoring any vibrations), and then release the OFF button.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
I had to hold the 'off' button for about 60 seconds before the phone vibrated and sprung into life - phew!

In my case there were no vibrations. I just held the button down for 120sec and it worked. Then I was able to flash back stock ROM
